Planet 03 · Terrestrial ocean world
The only known world with a living ocean.
Earth is the largest rocky planet and the only place known to host life. Liquid surface water, plate tectonics, a protective magnetic field, and a nitrogen-oxygen atmosphere make it unlike every other world we have examined.
World profile
About 78% nitrogen, 21% oxygen, and 1% other gases.
A moving rocky crust with continents, ocean basins, ice, and active plate tectonics.
Global average about 59 °F (15 °C)
One — the Moon
Composition
Field notes
Earth is the only planet known to keep stable liquid water on its surface.
The moving liquid-metal outer core generates the magnetic field that helps shield the atmosphere.
The leading model for the Moon's origin starts with a giant impact into the young Earth.

Second launch of 27 operational satellites for Amazon's Kuiper Systems internet constellation. The company is presently sending satellites to a 630 km LEO, which will include 34 orbital planes and 34 satellites per plane (1,156 total) at its final stage. The letter "A" in "KA-02" means "Atlas", which can be understood as second launch of Kuiper satellites on a ULA Atlas Rocket.
